Fixed issues where daemons such as Kea and ntpd did not correctly form
configuration file references to subinterface names [1150]

Fixed issues with clients on subinterface networks from receiving return
traffic that passes through TNSR [1152]

The upstream VPP issue causing this has been fixed, but an additional source
of problems in this area is that the dot1q setting for a subinterface must
use exact-match to communicate properly with hosts on the VLAN. Ensure
subinterfaces are configured to use this property.

Deleting a non-empty route table fails with an error and the table remains in
the configuration, but it cannot be changed afterward [1241]

Workaround: Remove all routes from the table before deleting. Alternately,
copy the running configuration to startup and restart TNSR, which will make
the route table appear again so the routes and then the table can be removed.
